What stats test should be used to solve the following? A positive psychologist compares whether levels of gratitude in a random sample of n = 50 students at her college (M = 40) differ from the mean of college students across the US (μ = 45). A sports psychologist tested the reaction time of 320 college athletes. She found their average reaction time in a controlled task to be .77 seconds (s = 21). She wondered if the college athletes had faster reactions times than college students on average, who typically reacted in 1.23 seconds. A school psychologist obtained a sample of 120 fourth-grade kids who engaged in remote learning only during the COVID-19 pandemic. She found their average anxiety score to be M = 168. He compared that mean to the average anxiety score of fourth-grade children before the pandemic, which was μ = 144, with a ?=12σ=12. Did the sample of kids engaged in remote learning have a significantly different level of anxiety?
